To will whom t may concern: y

Be it known that I, GEORGE MOORE, a citi# Zen of the United States,residing at Boston,

in the county of-Suffoll, State of Massachul setts, have invented acertain new and useful Improvement in Machines for Embossing andPrinting Upon Leather, Silk, and other Material, of which the followingis a specification, reference being had therein to the accompanyingdrawings. I My invention consists in a machine of novel and improvedcharacter which I have designed for use more particularly in printing ingold, silver, &c., upon leather, silk, and other material. I

I have shown in the accompanying drawings a machine embodying myinventionin the best form in which it has thus far been reduced topractice by me.

In the drawings, Figure 1 shows the said machine in side elevation. Fig.2 is an end elevation .of the said machine. Fig. 3, Sheet 3, is anisometric showing the platen and also a bar or plate with a sheet orstrip of leather or other material applied thereto in readiness forbeing embossed or printed. Fig. 4, Sheet 3,. is a sectional' detailshowing chiefly the mode of mounting the rack upon the platen. Fig. 5,Sheet 1, is an end elevation ofthe cylinder. Fig. 6,Sheet 3, is arepresentation of the cylinder in longitudinal section, showing certainof the burners thereof. I

Having reference to the drawings, the machine which is shown therein isprovided with a supporting-framework -comprising opposite side frames 11, which in their lower 4portions are connected by means o f a spacingand tie piece 2 and upon the tops of which a bed or table 3 is mounted,from the opposite sides of which rise the standards4 4, the saidstandards having the upper ends thereof connected by the pair of spacinand tie rods 5v5. 6 is a horizontal p aten located above and parallelwith the bed or table 3 and supported upon the latter by means of aseries of rolls 7 7, Sc'c'., intervening between the underl surfaceofthe platen andthe upper surface of the bed or plate and rolling uponthe latter surface as reciprocating movements are communicated to theplaten. The rolls 7 7, &c., are .arranged in groups upon the parallelcross-rods 71 71, &c., which latter have their opposite ends connectedto side bars 8 8, the extremities of the said side bars being joined byother rods 9 9. -The side bars and cross-rods 71 71 9 9 form arectangular frame y Specification of Letters Patent.

by means of which the rolls 7 7, &c., are maintained assembledlinworking relations; l From the opposite ends of the bed or table 3 pairsof arms 10 10 extend inthe direction of the length of the said bed ortable. ends of the said arms are upturned, and the upturned ends of eachof the said pairs are connectedby means of a cross-rod 11, on which ismounted a roll 12 between collars 121 121 on the said cross-rod, thesaid collars preventing the roll from movement lengthwise of thecross-rod The rolls 12 12 support the platen 6 as it approaches theextremes of its reciprocatory movements. rllhe platen is grooved on itsunderside at the middle of the width thereof and the bed or table` 3 isgrooved at its upper side, the grooves receiving projecting peripheralportions of the middle line of'rolls 7 7 and of the rolls 12 12. Therebythe platen is prevented from becoming misplaced transversely within themachine during operation.

The standards 4 4 are slotted vertically, and in the slots 41 of therespective standards are received the boxes 42 42, containingV the Thebearings for the shaft 131 of the cylinder 13.

The boxes 42 42 are supported by spiral springs 43, which are containedin the slots 41 of the standards, the lower ends of the said springsresting uponthe flat upper sides of semicircular blocks 44, occupyingthelower ends of the said slots. The springs 43 tend to raise the boxes42 42 andthe cylinder 13. Other springs 45 are placed within vthe slots41 abovethe boxes between plates 46, resting upon the latter and upperplates 47. The.l

said springs 45 are compressed between the said plates and tend to pressthe boxes and cylinder Y toward the platen with yielding force. Thetension of springs 45 is regulated at will by means of pressure-screws48 48, Working in threaded holes that are tapped in the upper ends ofthe standards 4 4 and taking bearing by their lower' ends against plates47 47. I

For the purpose of-enablingfthe cylinder 8 to be turned upon its axis ahand-wheel132 is mounted kupon one end of the shaft 131 thereof, thesaid end vprojecting beyond the bearing 42 at such side of the machineto receive the said hand-wheel.

The impression-surface is provided upon the cylinder 13 in practice,while the sheet or strip to vbe printed or embossed is supportedupontheplaten 6.

vAs thusl far described the machine is or i may be essentially asheretofore in platepresses, and the features, construction, andarrangement are not in themselves of the gist of the invention. l

In carrying my invention into effect in order that as the cylinder isturned upon its axis the platen may be moved lengthwise to present allportions of the length of the said sheet or strip properlyT to thedifferent portions of the said impression-surface the cylinder andplaten are geared together by means of a gear-wheel 133, with which oneend of the cylinder is formed or provided, and a rack 61, with which theplaten 6 is furnished. Thus when the cylinder` is partially rotated inone direction the platen is moved endwise in a corresponding directionto carry ythe sheet or strip resting thereupon past the cylinder toreceive an impression, and thenafter the said sheet or strip has beenremoved from the platen and replaced by another rotation of the cylinderin the opposite direction will be accompanied by travel of the platen inthe opposite direction, carrying the second sheet or strip past thecylinder .to receive an impression, and so on. To limit the closeness ofapproach of the surface of the cylinder 13 to the surface of the platen,the platen is-furnished at its opposite sides with ribs-62 62, extendinglengthwise of the same, and with the upper surfaces of which theperiphery of the body of the roll makes contact when not prevented fromso doing by the intervention of the sheet or strip that is to beembossed or printed and its backing between the impression-surface uponthe cylinder and the platen` I provide the cylinder 13 with animpression-surface which is constituted by a removable band or jacket14. The said bander jacket encircles the periphery ofthe cylinder andfits closely thereagainst. It is engraved lor cut upon its exteriorsurface according to the design, &c., which it is desired. to emboss orimprint. Preferably the said bandA or jacket is split transversely ordiscontinuous and is provided with means to clamp itr securely to theperiphery of the cylinder. In the illustrated embodiment of theinvention the opposite ends of the vband or jacket are furnished withblocks or lugs 141 141, which are formed with open-ended radial slots142, the said slots receiving the stem of a tightening and securing bolt143. An enlargement or head with which oneend of the said bolt isfurnished takes against the outer side of one lug, while a nut 144 uponthe threaded stem of the bolt takes against the outer side of the otherlug. By means of the bolt and nut the band or jacket may be tightenedupon the exterior of the body of the cylinder,` and thus effectivelysecured in place, while by unscrewing the said bolt and nut the band for jacket will be loosened. In order to enable the band or jacketconveniently to be applied to or removed from the cylinder, a space 135,corresponding in width with that of the band or jacket, is left at oneend of the cylinder between such end and the adjacent standard 4. Thisenables the band or jacket in being applied to be passed by a movementin a transverse direction with relation to the axis of the cylinder intothe said space. The opening between the ends of the bandv or jacketpermits such ends to be passed at opposite sides of the correspondingjournal of the cylinder, and after the band or jacket has been caused toassume concentricity with the periphery of the body of the cylinder theband or acket may be moved lengthwise of the said body into place uponthe body, after which the bolt 143 will be applied and tighti ened. Theremoval of the band or jacket is effected by the reverse operations, aswill be understood.

Provision is made for heating the cylinder as follows: In the oppositeheads of the cylinder are set pipes 16 16, &c., extending in thedirection of the length of the cylinder at suitable distances apartaround the axis of the cylinder. To the outer extremities of the saidpipes at the heads of the cylinder are fitted swiveling connections 161161, &c with which are joined flexible gas-supply pipes 162 162. In thecase of certain of the pipes 16 the swiveling connections 161 161 arecombined therewith at one end or head of the cylinder, while in the caseof the remainder, which alternate with those first referred to, theswiveling connections are combined therewith at the other end or head ofthe cylinder. Gas flowing through the supplypipes 162 162 passes by wayof the swive ing connections 161 161 into the interior of the pipes 1616. These last have iine holes 163 163 made through the shells thereof.Through the said holes the gas flows and is ignited, lie pipes 16 16,&c., constituting burners. addition the shaft of the cylinder is tubularand between the ends or heads of the cylinder is also furnished with anumber of holes 136 136, one outer end of the said shaft having acoupling 137 swiveled thereto, the said coupling having in connectiontherewith a supply-pipe 138. The shaft of the cylinder constitutes anadditional burner. templated that in practice gas will-be permitted toflow through the outlets or holes of the walls of the various burnersuntil the cylinder has become su'lliciently heated, after which the flowthrough the outer burners 16 In i ITO

It is con- 16, &c., willbe discontinued, leaving in aclis to be operatedupon and yproperly present-` ing the same to the action of theimpressionsurface ofthe cylinder I provide a bar or plate 17. This baror plate is rabbeted or reduced in thickness on the upper sidethereof atits` its end portions overlapping the` shoulders thereof, as in Fig. 3,in which the sheet or stri is designated 18, and then swinging the bai sdown, so as to depress the en`d portions of the sheet or strip aroundthe shoulders, which will cause the said end portions to be clampedbetween the shoulders and the cross portions of the bails. After thesheet or stripV 18 has been applied to the bar or plate 17 and its endportions have been clamped, as aforesaid, the said bar or plate is laidupon the platen 6, the latter being then in one of its eX- tremepositions. For the purpose of gaging the position ofthe bar or platewhen applied to the platen gage-pins 63 83 are provided upon the latter,and for engagement with the said gage-pins the ends-of thebaror plateare notched, as at 172. The bar or plate 17, with the sheet or strip 18of leather, silk, or other 'material .applied thereto, having been laidupon the platen, the cylinder is rotated by means of the hand-wheel inthe direction to advance the platen endwise with relation to thecylinder and cause'the impression-surface of the latter to act t'oemboss or print the said sheet or stri If the sheet or strip is to beprinted in go d, gold-leaf is laid upon the upper surface of the samebefore the bar or plate,with the sheet or strip thereon, is placed inposition upon the platen. y

In order to compensate for differences in the thicknesses of successivesheets or strips 18,' as well as variations in the thickness ofdifferent portions of a given sheet or, strip in the direction ofthelength of the latter, the vertically-movable boxes 42 42 of the cylinder13 are acted upon by the depressing-- springs 45, which cause thesurface of the t band or jacket 14 to bear with predetermined pressureagainst the upper surface of the sheet or strip. In order to enable theteeth of rack 61 to retain proper working relations with the teeth ofthe gear 133, which is connected withthe cylinder, the said rack islsup- -ported upon springs 65 65 on the platen 6 andlis movably securedto the platen. In this instance the rack is provided with a flange eX-tending downward alongside the corresponding edge of the platen, thesaid flange having vertical slots 66 66 &c., made transverselytherethrough, and the rack being held to the platen by means of screws67 67, the stems of which pass through the said slots into threadedholes that are 'tapped into the edge lof the platen.V The Vsprings andslots enable vthe rack to move vertically, and thereby accompany thegear-133 asthe cylinder rises and sinks.

, The. gear connection between the cylinder and platen insures a properregister between the embossing or printing surface of the ring, band, orjacket 14 upon the cylinder and the surface of a strip or sheetV ofmaterial carried by a work-holder that rests uponY the platen subjectedto a second or further pressure in case the impression7 or resultssecuredl by one passage through the press should prove insufi'cient orunsatisfactory. I claim as my inventionand is positioned by means of thework-holderv gages, enabling the saidband or sheet to be` 1.
